Whoever hijacked Young's verified account (@Neilyoung) tweeted various pornographic (NSFW) images, many of them retweets from the account of a prominent porn site. The hacker also sent out several expletive-laden tweets, adding the hashtag #neilslayed to some of them, apparently to draw attention to the hack.

One tweet admitted the account had been hacked, but that the situation had been "taken care of." However, many of the questionable tweets came after that tweet, which posted at 11:28 p.m. ET.

Please disregard my last few tweets. This account was hacked, but it has now been resolved and taken care of.

That tweet actually appears to have been the start of the hack, although it's unclear if any previous tweets were deleted. The account's last tweet before Friday night was on May 28, which promoted one of Young's albums being featured on a BBC radio station.

Another tweet from Young's account accused two other Twitter users of being behind the hack, but again, the claims are highly questionable. The hacker also replaced Young's photo with one from a seemingly random Tumblr.

John Hamm, CEO of Young-backed PonoMusic, confirmed the hacking to Mashable and said Young's management was in contact with Twitter about restoring the account to its rightful owner.

Neil Young recently had a very successful Kickstarter campaign for the PonoPlayer, an iPod-like device made specifically for high-resolution music. Although the campaign sought only $800,000, it ended up with pledges totaling more than $6 million. The first devices are expected to ship in late summer.
